This technique could be incorporated into situations even when you're not actually crying.
Here's a little story: I bought a t-shirt online. Based on the size chart it said it would fit me. I get it in the mail and the bust measurement is 4 inches smaller than the size chart said it would be. I was upset because it didn't fit and I would have to pay to send it back for a larger size. ANYWAY, I packaged it up to mail to the returns department, and head down to the office at my apartment complex to drop it in the mail. The office is supposed to open at 9am. I get there at 10:20 and there's a sign on the door saying they wouldn't open until 10:00. It was 10:20! So I walked all the way back to my apartment, too-small-shirt-package in hand, fuming silently at the office staff and at the website for misleading me with their size chart and costing me extra money in shipping charges.
It was a huge downer in the beginning of my day. I knew it was stupid to be so upset, and that I should just drop it, but I couldn't. I felt pissed off and couldn't shake it.
So I had a Non-Crying session. I threw the package on the floor, thought about the mean email I could send to the office staff about opening on time, and physically stomped around my apartment til I felt better. And that was it. I was done "crying" - turned my attention to my work and got back to business. Try it sometime.
